I have an array of Objects (file list excatly). How to iterate through this array and delete some Objects (in Java) - depending on the condition ?

File[] files = file.listFiles();

for(File f: files) {

if(someCondition) {

// remove

}

}

解決方案

I think the best Java way to tackle your problem is to convert your array into a list and use an iterator which allows you to remove objects:

List files = new ArrayList(Arrays.asList(file.listFiles()));

Iterator iterator = files.iterator();

while(iterator.hasNext()){

File currentFile = iterator.next();

if(someCondition){

iterator.remove();

}

// other operations

}

You can even convert it again into an array if necessary -even though handling a list is probably more convenient ...:

File[] filesArray = files.toArray();

總結(jié)
